For the purposes of capital gains tax, a married couple/civil partners can claim private residence relief for only one dwelling, even if they live apart.
Married/civil partners can possess joint property without needing to agree a contract.
In case of accident or illness of one spouse, the other is next of kin.
A spouse of a British citizen is entitled to a residence permit if the spouse is from the EU. If not, to apply for residence the British spouse must meet a minimum income requirement of at least £18,600 a year for the past six months. This rises to £22,400 for families with a child, and a further £2,400 for each further child.
A spouse may not be compelled by a criminal court to disclose private communications with their spouse.
When a married couple/civil partners separate, the courts have wide powers to divide their property and may set aside prenuptial agreements.
Wills are revoked on marriage or formation of a civil partnership (unless made in contemplation of marriage/formation of a civil partnership). Similarly, a divorced former spouse cannot benefit from a will made before divorce/dissolution.
The surviving spouse inherits part or all of the estate of a spouse who dies intestate. The exact rules for intestacy are different in the countries of the UK. In England and Wales, if there are children, the survivor inherits the first £125,000 plus personal possessions plus a life interest in half the remainder; if there are no children but the deceased has surviving parents or siblings, the surviving spouse inherits the first £200,000 plus personal possessions plus half the remainder; otherwise the survivor inherits the whole estate.
The surviving spouse is paid a proportion of their deceased spouse's pension. The exact amount has been a subject of legal challenge following the Marriage (Same Sex Couples) Act 2013: same-sex couples are only entitled to pass on a proportion of their pension since 2005 introduction of civil partnerships, considerably lowering the amount of pension provision they would pass on in the event of their death than if they had been married to an opposite sex partner. A legal challenge to change this failed in 2015.
Women who become spouses to male peers and knights usually receive titles which last for the length of a marriage. Men who are married to women who are made dames do not receive titles. In the case of same-sex partnerships, whether civil partnerships or marriages, the male spouse of an ennobled man does not get any title—nor would the female partner of a similarly ennobled woman. David Furnish, the husband of Sir Elton John, has argued that there still remains a legal inequality on this matter.
