Unmarried partners and stepchildren
Do not have any rights to inherit under the Intestacy Rules. Family structures can be complicated and a Will clearly sets out who you want to inherit and be maintained by you after you die. As importantly, it leaves out those who you don’t want to inherit from you just because you’re related by blood doesn’t mean you want them to benefit from you.
You may have started a second family but still want your children from your first relationship to benefit from your estate. Making a Will is critical in this situation.
Depending on how you hold your assets, your spouse may not have the automatic right to inherit all of your estate. There are limits and the Intestacy Rules decide how much they get. Your spouse could be forced to sell the family home to give those also entitled, their share of your estate.
