Answer

In England and Wales, no — it does not exist and has not for centuries. The belief that living together for a period creates marriage-like rights is one of the most widespread and consequential legal myths, and surveys repeatedly find that a large proportion of cohabiting couples believe it.

What cohabitants do not have, however long they have lived together:

No automatic claim on the other's property. Ownership follows the legal title and any recorded beneficial interest. A partner who moved into a home owned by the other, contributed to bills for twenty years and raised children there may have no claim at all on the house.

No right to maintenance for themselves on separation.

No automatic inheritance if the other dies without a will — the estate passes under intestacy rules to relatives, and a surviving partner may receive nothing.

No pension rights automatically, though many schemes allow nomination of a cohabiting partner and you must complete the form.

No right to make medical or funeral decisions, or to register the death in some circumstances.

Tax treatment that differs sharply, with none of the spousal exemptions.

What is unaffected: rights relating to children, which depend on parentage and parental responsibility rather than on the parents' relationship — child maintenance and arrangements apply regardless.

What can create a claim, in limited circumstances: contributions and agreements that establish a beneficial interest in property, which is complex, fact-dependent and expensive to litigate; a claim against an estate by a dependant; and a declaration of trust made deliberately.

What cohabiting couples should actually do: make wills, which is the single most important step; record property ownership explicitly, including shares; make a cohabitation agreement, which is enforceable as a contract if properly drafted; nominate each other on pensions and death-in-service benefits; and consider lasting powers of attorney.

Scotland differs, providing limited financial claims on separation and death for cohabitants — as do many other countries, which is part of why the myth persists.
