Is stepmom now entitled to anything from the house i.e. should we sell it?

Father re-married after first step mom passed. They had a living trust in both the stepmom’s kids whom 1 of 3 is still alive and my father’s 4 kids are still alive. After first stepmom passed, he remarried 2 years later but has never updated the trust to newer stepmom's name, been 13 years.
