Husband is an only child, and his parents have passed away. The real estate license is in his name, and the two children are underage. How can I transfer the property to my name?

Since your husband died, half of the property has been your husband's legacy. His heirs are you, his parents and your children. His parents are dead, and only you and your children are the heirs. You and your children inherit this part of his inheritance, and the property is yours and yours. Although minors can't give up inheritance, you can take care of their property as the guardian of children.
