Seven legal systems, twenty everyday arguments
Every cell below is a question, and every one of these systems has an answer to it. What differs is where the answer is kept. The filled cells hold a provision of the code and link to its official text; the rest name what answers it instead — an Act this collection does not carry, or the courts.

Who has a provision for what
Rows are problems, columns are legal systems. A cell with a citation in it links to the page reproducing that provision's official text. A cell without one names what answers the problem instead; select it to read the full note.
- The courts answer it No statute governs the point, and none is needed: the rule is judge-made. Negligence, private nuisance, Rylands v Fletcher, abatement, a common-law debt, deceit, caveat emptor — all of these are law, and none of them is in a code to quote.
- In law we don't carry The rule exists and is written down, in a statute outside the corpus behind these pages: special legislation, another code, or municipal law. This one is our limit, not the system's.
- No page written yet The provision is in the corpus these pages are built from and nobody has written it up. This is the one kind that is our gap rather than a finding, and it is listed so it can be closed.
A column total counts provisions of one code, not answers. It is not a score and it is not a measure of how much law a place has. England and Wales fills nine of these twenty cells and answers all twenty — much of its answer is judge-made, and a common-law system with a thin column here is a system that writes less of its law into codes, which is a fact about legal form and nothing else.
Where the answer is, when it is not in the code
Forty of the hundred and forty cells hold no provision, and none of them means the system is silent on the problem. Each was reached by putting the same question to every corpus and recording what came back, and each note names what does answer it. They fall into three kinds.
In law we don't carry
21 of 39The rule exists and is written down, in a statute outside the corpus behind these pages: special legislation, another code, or municipal law. This one is our limit, not the system's.

France Locked out: the landlord changed the locks and cut the power, in 7 jurisdictions
Code pénal, art. 226-4-2
France abolished the possessory actions — the reintegrande and the complainte — by loi n. 2015-177 of 16 February 2015, which repealed art. 2279 of the Code civil. The remedy moved wholesale to the juge des referes and to art. 226-4-2 of the Code penal, which makes it an offence to force an occupier out of his home without a court decision. So the Code civil genuinely has no article for this, and its absence here is a change in French law rather than a gap in the corpus.
-
France The tenant has stopped paying and will not leave: what the law says in six jurisdictions
Loi n° 89-462 du 6 juillet 1989
Recovering possession of a French dwelling is not Code civil business. It is loi n° 89-462 of 6 July 1989 and the code des procédures civiles d'exécution, neither of which is in the corpus behind these pages. The Code civil lease articles that survive — art. 1728 among them, which does have a page — state the tenant's duty to pay and to use the premises as agreed, but they no longer govern how a landlord gets a home back. This is the same shape of absence as French co-ownership, where the answer sits in the loi du 10 juillet 1965.
-
California Who stays in the family home: separation and the house in six legal systems
Family Code § 6321
A lookup miss rather than a gap in the law. California would answer this with Family Code § 2550, which requires equal division of the community estate and does have a page in this corpus, and with § 6321 on exclusive use of the dwelling, which does not. The lookup answered the custody half of the prompt instead and returned §§ 3040, 3044 and 3100, none of which is about the house. Rather than attach a member that does not answer the question asked, California is recorded as absent here; § 2550 answers who ends up owning what, which is a different question from who stays in the house while it is being decided.
-
United Kingdom A dog bit someone: what the law says in five countries
Animals Act 1971
Dog attacks in England and Wales are governed by the Animals Act 1971 and the Dangerous Dogs Act 1991. Neither is among the Acts this section carries — the UK corpus here holds the Children Act 1989, the Environmental Protection Act 1990, the Housing Act 1988, the Landlord and Tenant Act 1985, the Matrimonial Causes Act 1973, the Partnership Act 1890 and TOLATA 1996 — so there is no section to place beside the other five.
-
New York A dog bit someone: what the law says in five countries
Agriculture and Markets Law
New York's dog-bite rule lives in the Agriculture and Markets Law and in case law about an animal's vicious propensities. The New York corpus behind these pages covers the Domestic Relations Law, the General Obligations Law, the Partnership Law and the Real Property Law, none of which contains an animal-liability provision. The absence is a limit of the corpus, not a finding that New York has no rule.
-
California Siblings inherited the house and one will not sell: what the law says in 7 jurisdictions
The Probate Code
Administration of a deceased person's estate in California is governed by the Probate Code, which is not in this corpus, so there is no page to link. The lookup returned nothing with a page. California does have a partition procedure for co-owned real property, but it sits outside the Civil Code sections published here.
-
New York Siblings inherited the house and one will not sell: what the law says in 7 jurisdictions
EPTL; SCPA
The same: New York's succession law is the Estates, Powers and Trusts Law together with the Surrogate's Court Procedure Act, neither of which is in this corpus. The lookup produced RPL § 240-c, on severing a joint tenancy, which is a different mechanism — it operates between living co-owners and does not address the division of an estate among heirs.
-
Italia The landlord kept the deposit: how five legal systems decide who was right
L. 392/1978, art. 11
The Codice Civile contains no security-deposit provision. The three-month cap and the obligation to pay legal interest on an Italian residential deposit are art. 11 of L. 392/1978, a housing statute outside this corpus. A lookup returned arts. 1590 and 1587 on the condition of the property at handover, which answer the deduction question but not the deposit question, so Italy is recorded as absent rather than represented by a near-miss.
-
United Kingdom The landlord kept the deposit: how five legal systems decide who was right
Housing Act 2004, ss. 212-215
Deposit protection in England and Wales is Housing Act 2004 ss. 212-215 - the tenancy deposit schemes, the prescribed information and the penalty of one to three times the deposit - and that Act is not in the UK corpus. A lookup reached instead for Housing Act 1988 s. 21, which is about ending an assured shorthold tenancy and is the wrong end of the tenancy entirely.
-
United Kingdom The builder did the work badly and will not come back: what the law says in 7 jurisdictions
Defective Premises Act 1972
The Defective Premises Act 1972 and the Building Act 1984 are not in this corpus, and outside them a botched bathroom in England is an ordinary breach-of-contract claim developed by the courts rather than a code guarantee. The lookup returned nothing from the Acts the corpus does hold.
-
California The builder did the work badly and will not come back: what the law says in 7 jurisdictions
Civ. Code §§ 895-945.5
California does have a construction-defect statute — Civ. Code §§ 895 to 945.5, the SB 800 regime — but it has no pages in this section, so there is nothing here to link to. The lookup instead offered rescission under §§ 1689 and 1691 and the damages measure at § 3333, which are general contract law and not a builder's guarantee.
-
L. 392/1978; L. 431/1998
Residential rent and its indexation in Italy are L. 392/1978 and L. 431/1998, not the Codice Civile. The code governs the general obligations of landlord and tenant and stops there: the lookup answered with arts. 1575 and 1587, which set out what each party owes the other and say nothing about increases. Italy is absent from this comparison because the Italian answer was legislated out of the civil code decades ago.
-
Loi n° 89-462, art. 17-1
The same in France: revision of a residential rent is art. 17-1 of the loi n. 89-462 and the IRL index published by INSEE, both outside the Code civil. The lookup found only art. 1103, that lawfully formed contracts bind the parties - true, and useless to a tenant facing a large increase.
-
Ley de Arrendamientos Urbanos, art. 18
The same again in Spain: rent revision on a residential lease is art. 18 of the Ley de Arrendamientos Urbanos. The lookup returned arts. 1556 and 1569 of the Codigo Civil, which are about breach of the lease and grounds for eviction - a neighbouring subject, not this one.
-
United Kingdom The other parent stopped paying: child maintenance in four civil codes
Child Support Act 1991
Child maintenance in England and Wales is assessed administratively by the Child Maintenance Service under the Child Support Act 1991 formula, and the courts are largely ousted from setting the amount. Nothing in the UK corpus answers the question 'how much'. The lookup reached for Matrimonial Causes Act 1973 ss. 23 and 25, which are the financial provision and property powers between spouses, not the child maintenance calculation - so the absence here is a real feature of English law rather than a gap in the corpus.
-
California The other parent stopped paying: child maintenance in four civil codes
Family Code § 4055
California's guideline formula is Family Code § 4055, which has no page in this corpus. The lookup returned §§ 3010 and 3028, neither of which is a page and neither of which is about the amount of support. The contrast with the civil codes is the point: California legislates an algebraic formula where Italy, France, Spain and Germany legislate a proportionality standard.
-
New York The other parent stopped paying: child maintenance in four civil codes
DRL § 240(1-b)
New York's percentages are in Domestic Relations Law § 240(1-b), the Child Support Standards Act, which has no page here. The lookup found DRL § 244, which turns arrears into a money judgment, and § 248 - both enforcement provisions rather than provisions about the amount. New York therefore appears in this corpus on the question of collecting child support and not on the question of setting it.
-
United Kingdom Who owns the boundary wall and who pays to repair it: 4 civil codes, and 3 systems with no rule at all
Party Wall etc. Act 1996
Party walls in England and Wales are governed by the Party Wall etc. Act 1996, which is not in this corpus — and which in any event works differently from the four codes above: it regulates notices, awards and surveyors for works affecting a party wall rather than presuming who owns it. Ownership itself comes from the conveyance and from the facts on the ground. The lookup returned nothing from any Act the corpus does hold.
-
France Who pays for the roof and the lift: shared building costs in four legal systems
Loi du 10 juillet 1965
The textbook case of an answer living outside the code. French co-ownership of a building is the loi n. 65-557 of 10 July 1965, a free-standing statute; the Code civil says nothing about a syndicat de coproprietaires, a reglement de copropriete or a repartition of charges. A lookup across the whole Code civil returned no article with a page - correctly, because there is nothing there to return.
-
Deutschland Who pays for the roof and the lift: shared building costs in four legal systems
Wohnungseigentumsgesetz
The same, and less widely known outside Germany: German condominium is the Wohnungseigentumsgesetz, not the BGB. The lookup did return §§ 741 and 745 on the Bruchteilsgemeinschaft, which look plausible to a non-specialist and are the wrong body of law - a fractional community of co-owners is not Wohnungseigentum, and the WEG has its own rules on Kostenverteilung and Beschlusskompetenz. Both are left out rather than published as a false equivalent.
-
California Who pays for the roof and the lift: shared building costs in four legal systems
Davis-Stirling Act
California common-interest developments are governed by the Davis-Stirling Common Interest Development Act, Civil Code §§ 4000 and following, which has no pages in this corpus. The lookup offered §§ 1430-1432 and 1468, none of which is a page and none of which is the operative law for an HOA assessment.
The courts answer it
16 of 39No statute governs the point, and none is needed: the rule is judge-made. Negligence, private nuisance, Rylands v Fletcher, abatement, a common-law debt, deceit, caveat emptor — all of these are law, and none of them is in a code to quote.
-
New York Noise from the neighbours: what the law says in seven countries
Private nuisance; NYC Noise Code
New York has no noise or nuisance provision in the Consolidated Laws. Private nuisance in New York is common law, developed by the courts rather than enacted, and the decibel limits and quiet hours people actually cite are the New York City Noise Code in title 24 chapter 2 of the Administrative Code, which is municipal law and outside this corpus. A lookup across the whole of the Consolidated Laws for this problem returned nothing, which is the correct answer rather than a gap in the corpus.
-
United Kingdom Someone's child damaged my property: what the law says in six jurisdictions
The parent's own negligence
The most interesting absence in this comparison, because it is the law rather than a missing page. In England a parent is not vicariously liable for a child's torts at all. Liability arises only where the parent was themselves negligent — in supervising, or in putting something dangerous in a child's hands — and that is a common-law negligence claim, not a statutory provision. A lookup over the Acts this section carries returned nothing, which is the correct answer rather than a gap.
-
United Kingdom The seller knew about the defect and said nothing: what the law says in 7 jurisdictions
Caveat emptor; Misrep. Act 1967
Caveat emptor survives on the sale of a house in England and Wales: there is no statutory warranty of condition and no general duty on the seller to volunteer what he knows. The buyer's routes are a survey, the replies given to pre-contract enquiries, and the Misrepresentation Act 1967 where a reply was untrue — and neither the 1967 Act nor the conveyancing practice around enquiries is in this corpus. The lookup returned nothing.
-
United Kingdom I lent a friend money with nothing in writing: what the law says in five jurisdictions
A common-law debt
A simple loan in England and Wales is a common-law debt, with no statutory provision creating or governing it. The Acts this section carries — the Children Act 1989, the Environmental Protection Act 1990, the Housing Act 1988, the Landlord and Tenant Act 1985, the Matrimonial Causes Act 1973, the Partnership Act 1890 and TOLATA 1996 — contain nothing on lending, and England's own writing requirement for guarantees sits in the Statute of Frauds 1677, which is not among them.
-
United Kingdom Sold as seen: the second-hand car that broke down, in four civil codes and three common-law systems
Satisfactory quality in England and Wales is s. 14 of the Sale of Goods Act 1979 and, for consumer sales, the Consumer Rights Act 2015 - neither of which is in this corpus. Even if they were, neither would help here: the implied term as to satisfactory quality applies where goods are sold in the course of a business, so a purchase from a private seller falls outside it. The lookup returned nothing, and that is the right answer twice over.
-
California Sold as seen: the second-hand car that broke down, in four civil codes and three common-law systems
Fraud, not warranty
A private used-car sale in California carries no implied warranty of quality. The buyer's route is deceit, and the lookup found precisely that - §§ 1572, 1709 and 1710 on fraud. That is a different cause of action with a different element set: the buyer must prove a misrepresentation or a concealment and the seller's state of mind, where the four civil codes impose liability without either. California is therefore recorded as absent from the warranty cluster and present in the separate comparison on a seller who hid a defect.
-
New York Sold as seen: the second-hand car that broke down, in four civil codes and three common-law systems
Fraud, and the contract
The same position. Nothing in the New York Consolidated Laws pages answers a private used-goods sale; the used-vehicle warranty statute, Vehicle and Traffic Law s. 417, applies to dealers only. A New York buyer from a private seller is left with fraud and with whatever the contract itself says.
-
New York The builder did the work badly and will not come back: what the law says in 7 jurisdictions
Breach of contract
New York has no construction-defect statute among these pages. The lookup found GOL § 5-322.1, which voids indemnity clauses in construction contracts. It is a real and useful section, and it answers a different question: who bears the risk between the parties to a building contract, not what an owner may demand when the work is bad.
-
United Kingdom The neighbour's tree hangs over my garden: what the law says in four countries
Abatement: common-law self-help
Cutting back an overhanging branch in England and Wales is abatement, a common-law right of self-help. There is no section on it, so there is nothing to reproduce verbatim and nothing to compare. A lookup over the Acts this section carries answers with the statutory nuisance regime of the Environmental Protection Act 1990, which does not reach overhanging vegetation.
-
California The neighbour's tree hangs over my garden: what the law says in four countries
Abatement, at common law
Self-help abatement is common law in California too. The corpus does hold a real and closely related section — Civil Code § 3346, which has its own page — but it answers the opposite question: the damages, potentially trebled, payable by someone who injures a neighbour's tree. It is what you consult before cutting, not the authority to cut.
-
New York The neighbour's tree hangs over my garden: what the law says in four countries
Nothing statutory. The New York corpus behind these pages covers the Domestic Relations, General Obligations, Partnership and Real Property Laws, and none of them contains an encroaching-vegetation provision; the lookup returned nothing rather than stretching a section that was there.
-
United Kingdom Water coming through the ceiling from the flat above: what the law says in 7 jurisdictions
Negligence, nuisance, Rylands
There is no Act of Parliament on water escaping between flats. A leak from upstairs is negligence, private nuisance or Rylands v Fletcher, all developed by the courts. The statutes the lookup reached for — LTA 1985 s. 11 and EPA 1990 s. 79 — answer the different question of a tenant against a landlord, or of a statutory nuisance against a local authority, not of one flat owner against another.
-
California Water coming through the ceiling from the flat above: what the law says in 7 jurisdictions
Negligence
California has a general duty clause, Civ. Code § 1714, and a nuisance definition, § 3479, and neither is a rule about escaping water. They set the frame in which a negligence claim is argued; they do not decide who bears the loss when a pipe fails.
-
New York Water coming through the ceiling from the flat above: what the law says in 7 jurisdictions
Common-law negligence
Same. The statute the lookup produced, RPL § 235-b, is the warranty of habitability, which the § 235-b page itself points out speaks only to the landlord's obligation under the lease: 'If a neighbor's plumbing caused the damage, § 235-b still speaks only to the landlord's obligation.' Neighbour against neighbour is common-law negligence.
-
The deed, or an easement
There is no California code section presuming a boundary wall to be shared. Party-wall rights come from the deed, from an easement, or from common law, and the lookup returned nothing. Where a civil-law neighbour can start from a statutory presumption, a Californian one starts from the title documents and whatever the parties or their predecessors agreed.
-
The deed, or an easement
The same. New York has no statutory presumption of party-wall ownership in the Consolidated Laws pages, and the lookup returned nothing. Party-wall rights in New York are typically created by deed or by an easement recognised at common law, and disputes are argued from those documents rather than from a code article.
No page written yet
2 of 39The provision is in the corpus these pages are built from and nobody has written it up. This is the one kind that is our gap rather than a finding, and it is listed so it can be closed.
-
New York Separated parents who cannot agree where the children live: what the law says in six jurisdictions
DRL § 240
New York decides custody under Domestic Relations Law § 240 and the Family Court Act. DRL § 240 is in the corpus these pages are built from — the gap here is a page, not a law. The New York pages reach § 241 (withholding visitation and maintenance) and § 72 (grandparent visitation and custody) but not § 240 itself, so New York cannot be listed as a member without a link to a page that does not exist. A page on DRL § 240 would close this.
-
Italia I lent a friend money with nothing in writing: what the law says in five jurisdictions
Cod. civ. artt. 1813-1820
Not a gap in the law but a gap in the pages, and the only one of its kind in this comparison. The Italian mutuo is art. 1813 of the Codice Civile — "il contratto col quale una parte consegna all'altra una determinata quantita' di danaro o di altre cose fungibili, e l'altra si obbliga a restituire altrettante cose della stessa specie e qualita'" — and it is in the corpus these pages are built from, along with arts. 1814, 1816, 1817 and 1820. No page has been written for any of them, so listing Italy here would mean a link to nothing. It is worth writing.
The label sorts the note; the note is the finding. Both are shown together everywhere, because "the courts decide this one" and "the rule is in an Act we do not carry" are different facts, and neither of them is "there is no rule".
What each collection actually holds
Page counts and how they fall across each section's own themes. The themes are not a shared taxonomy and are not forced into one: Italy groups by condominio, New York by which of four Consolidated Laws a section sits in. What is comparable is the shape.

That's the map. Now let's settle your problem.
Say what is happening. A neutral mediator hears your side and the other party's, and walks you both to a written agreement. In the advanced settings you can ask for the decision to be reasoned on the law of one of these jurisdictions.
Or open a session directly and invite the other party.
This page maps provisions of several legal systems and links to the official text of each. It is not legal advice, it does not tell you which country's law governs your situation, it does not say which system would be better for you, and it takes no account of the circumstances of your case. For a live dispute, consult a qualified lawyer in the jurisdiction concerned.
