Only jointly owned assets will pass to your partner. Your personal estate will pass through your family in accordance with the above section, as cohabitees are legally treated as single people. There are no plans within the term of the present coalition government to amend these rules. Cohabitees can make a claim under the Inheritance (Provisions for Family and Dependents) Act 1975, but this is likely to be costly, drawn-out, uncertain and stressful. Generally, Courts do not treat cohabitees in the same way as disinherited spouses when awarding benefits from your partner’s estate. Sadly, this is not the only inheritance planning problem facing co-habitees with or without a will.
