The law is about planning for the best, but being prepared against the worst. In the case of families with minor children, that worst would be the loss of parents. A guardianship permits a non-parent to make decisions for, and care for, a minor child and/or that child's estate. The importance of choosing a guardian for your child and documenting that choice in a will cannot be overstated. Non-parents (such as grandparents) who find themselves with a minor child to raise need a guardianship so that the law supports their time and energy spent on behalf of the child.
