§ 3127.18.

(A) A court of this state has temporary emergency jurisdiction if a child is present

in this state and either of the following applies: (1) The child has been abandoned. (2) It is necessary in an emergency to protect the child because the child, or a sibling

or parent of the child, is subjected to or threatened with mistreatment or abuse. (B) If there is no previous child custody determination that is entitled to be enforced

under this chapter and a child custody proceeding has not been commenced in a court

of a state having jurisdiction under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state, a child custody determination made under this

section remains in effect until an order is obtained from a court of a state having

jurisdiction under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state.  If a child custody proceeding has not been or is not commenced in a court of a state

having jurisdiction under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state, a child custody determination made under this

section becomes a final determination, if it so provides and this state becomes the

home state of the child. (C) If there is a previous child custody determination that is entitled to be enforced

under this chapter, or a child custody proceeding has been commenced in a court of

a state having jurisdiction under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state, any order issued by a court of this state

under this section must specify in the order a period that the court considers adequate

to allow the person seeking an order to obtain an order from the state having jurisdiction

under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state.  The order issued in this state remains in effect until an order is obtained from

the other state within the period specified or until the period expires. (D) A court of this state that has been asked to make a child custody determination under

this section, upon being informed that a child custody proceeding has been commenced

in or a child custody determination has been made by a court of a state having jurisdiction

under sections 3127.15 to 3127.17 of the Revised Code or a similar statute of another state, shall immediately communicate with the other

court.  A court of this state that is exercising jurisdiction pursuant to sections 3127.15 to 3127.17 of the Revised Code , upon being informed that a child custody proceeding has been commenced in or a child

custody determination has been made by a court of another state under a statute similar

to this section, shall immediately communicate with the court of that state to resolve

the emergency, protect the safety of the parties and the child, and determine a period

for the duration of the temporary order.
