Final answer:
The transfer of custodial responsibility and the signing and dating of an updated copy of the CRL is typically done by the legal guardians or parents.
Step-by-step explanation:
In the context of law, the transfer of custodial responsibility and the signing and dating of an updated copy of the CRL (Custodial Responsibility Letter) is typically done by the legal guardians or parents. This is done to officially document and acknowledge the transfer of legal responsibility for a child or minor.
For example, when a custodial parent is unable to care for their child temporarily, they may transfer custodial responsibility to another trusted adult, such as a grandparent or close family member. The legal guardians or parents would then sign and date an updated copy of the CRL to indicate this transfer.
