Firm proposals on the future of Sheriff Courts in Peebles, Duns and Kirkcudbright will be revealed today.
The Scottish Courts Service says it needs to reduce the number of court buildings to save money after a twenty per cent reduction in its budget.
The Justice of the Peace Court in Annan is also under threat of closure.
Opponents argue that visible access to local justice will be compromised.
There are also concerns that many people living in rural areas will struggle with transport costs.
A final decision on court closures will be taken by the Scottish Government.
