Short answer. It's restricted. Rule 102, Section 18 bars removing a person committed for a criminal matter to another officer's custody except by legal process, delivery to an inferior officer to carry to jail, court-ordered transfer for trial, or necessity like fire, epidemic, or public calamity, with a one-thousand-peso forfeiture for violators.

What the law says

A person committed to prison, or in custody of an officer, for any criminal matter, shall not be removed therefrom into the custody of another officer unless by legal process, or the prisoner be delivered to an inferior officer to carry to jail, or, by order of the proper court or judge, be removed from one place to another within the Philippines for trial, or in case of fire, epidemic, insurrection, or other necessity or public calamity

The default rule against transfer

A person committed to prison, or in custody of an officer, for any criminal matter, shall not be removed therefrom into the custody of another officer except in the specific situations the section then lists. This default rule applies regardless of how convenient a transfer might be for the custodian, meaning a jail cannot move a detainee to a different facility or hand them to a different officer simply because it is administratively easier, unless the move falls within one of the recognized exceptions.

The permitted exceptions

Transfer is allowed by legal process, where the prisoner be delivered to an inferior officer to carry to jail, by court or judge's order to remove him from one place to another within the Philippines for trial, or in case of fire, epidemic, insurrection, or other necessity or public calamity. Each exception covers a scenario where either judicial oversight already exists, as with legal process or a court order, or where an emergency genuinely leaves no time to obtain one, such as a fire threatening the jail itself or a calamity forcing an evacuation.

Why the restriction exists

Unrestricted transfers between custodians could otherwise be used to frustrate a pending or future habeas corpus petition, by making the prisoner harder to locate or the proper respondent unclear. If a jail could freely shuffle a detainee between officers, a family member seeking habeas corpus relief might struggle to even identify the correct custodian to name in the petition, and any writ issued could arrive at the wrong hands entirely.

The penalty for an unauthorized transfer

A person who, after commitment, makes, signs, or countersigns any order for such removal contrary to the section shall forfeit to the party aggrieved the sum of one thousand pesos, to be recovered in a proper action. This penalty attaches personally to whoever authorized the unlawful transfer, giving the aggrieved party, typically the detainee or their family, a direct civil remedy separate from any habeas corpus petition, and giving custodians a concrete financial disincentive against sidestepping the rule.
