My in-laws are claiming a share of my late husband's estate. Are they really entitled to it?

Yes, if your late husband's mother or father was still alive when he died, they are lawful heirs. Many widows are surprised because they assumed a husband's property is only for his wife and children. In fact, the deceased's parents have fixed shares that do not fall away even if he had children. Their claim is not a sign that they do not love you. They have also lost a son, and may have depended on him all this time. Make sure your jointly acquired property (harta sepencarian) is determined first, because that portion is not part of the estate. Then let the faraid certificate set each person's share. If conversations feel tense, speak to your in-laws through a respected family member. See in-laws.
