The laws surrounding grandparent's visitation rights is currently in a state of flux. A number of important courts decisions have come down over the past few years, but every state has different rules and laws. Courts grant visitation or custody to grandparents only when certain conditions provided in state statutes are met. Conditions for a grandparent to attain custody differ from those conditions required for visitation rights. A grandparent should be familiar with the conditions for either custody or visitation before determining whether to file a petition to request either from a court of law.
