Full Text of Rule 1657
Plain-English Summary
This rule keeps a mechanics’-lien action focused. The plaintiff may not join any other cause of action with the action to obtain judgment on the lien claim, with a narrow exception for the case where the improvement is located in more than one county and claims have been filed accordingly.
Confining the suit to enforcing the lien keeps the proceeding tied to the recorded claim and the statutory remedy, rather than letting it expand into general contract or other disputes that belong in an ordinary action.
Frequently Asked Questions
Can other claims be joined with a mechanics' lien action?
No, except that lien claims on the same improvement filed in more than one county may be joined.
