Does a change in marital status affect my will?
Marriage and divorce both have effects on a will.
I have already made a will, and subsequently got married
Getting married could revoke a will made before the marriage, unless the will is specifically made in contemplation of that marriage.
If you get married it is better to draft a new will to ensure there is no question of revocation.
I have already made a will, and subsequently got divorced
Divorce can completely invalidate a will, depending on your state.
It is better to create a new will following divorce so there is no question of validity.
