The South Yorkshire Mayoral Combined Authority (SYMCA) is to decide whether to grant £3.1m to support the purchase of Doncaster Sheffield Airport.
The authority's board will meet later to discuss a request from Doncaster Council for funding for legal action to force owners Peel Group to sell the site.
Peel closed the airport in November, saying it was not financially viable.
The council is considering pursuing a compulsory purchase order (CPO.)
In April, the local authority agreed to set aside £3.1m towards the costs of taking legal action. It said a CPO would only be needed if all other avenues, such as a negotiated sale or lease, were exhausted.
The council has asked SYMCA for financial support for "the costs of building a case", a report to the SYMCA's annual general meeting said.
