What is my husband's father to me?
Your husband's father is your father-in-law. Your spouse's parents become your parents-in-law the day you marry — one of the few marriage links English gives a fixed, formal name. No blood connects you; the relationship exists entirely through the marriage, and it makes you his child-in-law in return.

From the other side, you are their child-in-law.
This connection runs through a marriage, not a shared ancestor, so the ancestor chart can't draw it.

This relationship sits outside the shared-ancestor model, so the card above carries the answer and the calculator opens in its default state. Work out any blood relationship with it, or open the full relationship calculator.
