From whom?
No they can not.
see link below
She actually can as long as her oldest daughter is over 18 years old. when you are 18 you are a legal adult and now responsible so they could actually sign it over to your oldest daughter as long as she is old enough. The court would need to approve the guardianship and the father would need to also consent.
If mother transferred her property to her daughter by deed, the deed was recorded and then her daughter died, the property would pass to the daughter's estate. It would then pass to the daughter's heirs according to her will or to the state laws of intestacy if she had no will.
If he is not the father of the child, he has no rights to sign over.
On the back of the title there is a place to sign it and the person that is receiving the car signs it as well.
You can remove the dad's name by getting another title assigned. The dad will need to sign over the rights to the car to the daughter.
If approved by the court, no as it is similar to an adoption.
yup
Yes, unless/until the child is adopted.
Can only a mother sign for her 17 year old daughter to get married?
if the grandmother has current custody i think so depends on the provinces/states laws
