A property adjustment order refers to an order changing the ownership of property held by a separating couple. This might be the family home or other property. Such orders will only arise within the context of a hearing for separation/divorce.
THIS refers to inheritance rights. Separation does not necessarily put an end to a spouse’s right to inherit.
After separation the parties remain for legal purposes ‘spouses’. However, in practise most judges will grant mutual waivers of succession rights if asked to adjudicate the matter.
In some cases, usually by agreement, spouses may keep their rights pending a divorce. The fact of a divorce puts an end to any succession rights as the parties are no longer spouses.
