Families with children who are adopted, or stepchildren who haven’t been legally adopted, may face unique estate planning challenges. Additional consideration must be taken when a family includes an unmarried couple in a long-term relationship and one person has biological or adopted children. If your family’s makeup is as such, it’s important to understand your estate planning options.

Treated As Equals
Adopted children are placed on an equal footing with biological children in most situations for estate planning purposes. Thus, adopted and biological children are treated the same way under a state’s intestate succession laws, which control who inherits property in the absence of a will.

In addition, adopted children generally are treated identically to biological children for purposes of wills or trusts that provide for gifts or distributions to a class of persons, such as ‘children,’ ‘grandchildren,’ or ‘lineal descendants’ — even if the child was adopted after the will or trust was executed.

No Inheritance Rights Unless Adopted
Stepchildren generally don’t have any inheritance rights with respect to their parents’ new spouses unless the spouse legally adopts them. If you have stepchildren and want them to share in your estate, either adopt them or amend your estate plan to provide for them expressly.

Of course, estate planning isn’t the only reason to adopt stepchildren. Adoption also gives you the legal rights of a parent during your life.

Before you adopt stepchildren, however, you and your spouse should consider the potential effect on their ability to inherit from (or through) their other biological parent and their relatives. In most states, when a child is adopted by a stepparent, the adoption decree severs the parent-child relationship with the other biological parent and his or her family. That means the child can’t inherit from that biological parent’s branch of the family — and vice versa — through intestate succession.

Second-Parent Adoption Considerations
A growing minority of states now permit second-parent adoptions, in which an unmarried person adopts their partner’s biological or adopted children without terminating the partner’s parental rights. However, in states that recognize second-parent adoptions, their intestate succession laws may not provide for a child to inherit from the ‘second parent.’

Spell Out Your Wishes
If you have children who are adopted, stepchildren whom you haven’t legally adopted, or you’re unmarried but in a long-term relationship and your partner has biological or adopted children, clearly address your intentions in your will or living trust.
