A stepchild is a child that your spouse had before you got married or legally adopted before you became their parent. If you adopt them, they become your child just like if you had them biologically. In some places, stepchildren have the same rights and responsibilities as biological children, but this can vary depending on the law. For example, if you want to leave property to your children in your will, the law might decide if stepchildren count as children. If you want to claim your stepchild as a dependent on your taxes, they usually have to live with you for more than six months and be younger than you.
A stepchild is a child who is the biological or legally adopted child of your spouse from a previous relationship. If you have not legally adopted the child, they are still considered your stepchild. However, if you do legally adopt the child, they become your legal child and have the same rights as if they were biologically related to you.
The relationship between a stepchild and stepparent has different implications in different areas of law. For example:
If you leave property to your children in your will, state law will determine whether a stepchild qualifies as a child when used generally in a will and whether it means only biological children.
In order for a stepchild to be able to immigrate as a "child," the marriage creating the stepchild/stepparent relationship must have happened before the stepchild was 18 years of age.
If you want to claim your stepchild as a dependent on your tax returns, the IRS states that your stepchild must live with you for more than six months of the calendar year, and the child has to be younger than you are unless the child has a permanent disability.
