(a) Concurrent Jurisdiction. Only the court may grant an extension of time for any act required by these rules. Before the record is transmitted, the lower tribunal shall have concurrent jurisdiction with the court to render orders on any other procedural matter relating to the cause, subject to the control of the court. 

(1) The lower tribunal shall retain jurisdiction to enter and enforce orders awarding separate maintenance, child support, alimony, attorneys' fees and costs for services rendered in the lower tribunal, temporary attorneys' fees and costs reasonably necessary to prosecute or defend an appeal, or other awards necessary to protect the welfare and rights of any party pending appeal. 

(2) The receipt, payment, or transfer of funds or property under an order in a family law matter shall not prejudice the rights of appeal of any party. The lower tribunal shall have the jurisdiction to impose, modify, or dissolve conditions upon the receipt or payment of such awards in order to protect the interests of the parties during the appeal. 

(3) Review of orders entered pursuant to this subdivision shall be by motion filed in the court within 30 days of rendition.
