I dont think so
If they do not have custody of the children, they cannot. If they have custody, they can apply to a court for a name change.
All possibilities exist.
No. A stepparent has no legal authority in regards to non biological children. He or she cannot give a stepchild permission to marry, leave the custodial parent or any other legal issue. If one biological parent has sole custody he or she can give the minor child permission to marry. If both biological parents share custodial rights, both must give permission for an underaged minor to marry.
If no court order is in place stating otherwise, the biological mother has presumptive custody of her children.
It depends on how your custody agreement is written.
If a biological dad has custody and placement of his children and the mother remarries, is the her new husband suddenly a stepfather?
Marriage by itself does not bring custody rights to non-biological children. Where the children go when the biological mother dies depends on who has custody, whether the non-biological father has adopted the child, whether the biological father wants the child, and on the laws of the state where all of this is happening.
no, only if you are going out of the country. I just traveled out of state with my 2 children and I have sole physical custody, it was no problem.
Not without the permission of the child's biological mother. When a couple are not married and there is not a custodial order from the court, the law presumes that the mother has sole custody of the child in question.
Their biological father.
When it pertains to custodial issues related to minor children all US states have laws that allow for sole and joint custody by the biological parents.
Your husband cannot get joint custody of your children from a prior marriage. Custody arrangements are made between parents of children. Your present husband can legally adopt your children with their father's consent. He would then have all the legal rights and obligations of a biological father. The children would become his legal heirs-at-law.
