(A) A service member who is entitled to a stay in civil proceedings pursuant to the Service Members Civil Relief Act, 50 U.S.C.

Testimony presented must be made under oath, in a manner viewable by all parties, and in the presence of a court reporter. In matters when a party who is physically present in the State is permitted to use affidavits or seek temporary relief, the service member may submit testimony by affidavit. (B) The court must allow a party to proceed pursuant to this section unless an opposing party establishes a compelling reason not to proceed by clear and convincing evidence. The court must allow a party to present evidence pursuant to a method provided by this section unless an opposing party established that the method will cause a substantial injustice, deny effective cross examination, deny the right to confront the witness, or abridge another constitutional right.
