Full Text of Rule 161

Text size

When some of the several defendants in a suit are served with process in due time and others are not so served, the plaintiff may either dismiss as to those not so served and proceed against those who are, or he may take new process against those not served, or may obtain severance of the case as between those served and those not served, but no dismissal shall be allowed as to a principal obligor without also dismissing the parties secondarily liable except in cases provided by statute. No defendant against whom any suit may be so dismissed shall be thereby exonerated from any liability, but may at any time be proceeded against as if no such suit had been brought and no such dismissal ordered.

Plain-English Summary

Rule 161 gives the plaintiff options when some defendants are served in time and others are not. The plaintiff may dismiss as to those not served and proceed against those who are, take new process against the unserved, or sever the case between the two groups. One limit protects sureties: a principal obligor cannot be dismissed without also dismissing the parties only secondarily liable, except where a statute allows.

A dismissal under this rule is not an exoneration. A defendant dismissed for want of service may be proceeded against later as if no suit had been brought and no dismissal ordered.

Frequently Asked Questions

What can a plaintiff do about defendants who weren't served in Texas?

Under Rule 161, dismiss as to the unserved and proceed against the served, take new process, or sever — except a principal obligor cannot be dropped without the secondarily liable parties. A dismissed defendant can be sued again.

Does dismissing an unserved defendant release them from liability in Texas?

No. Rule 161 says a defendant dismissed for want of service is not exonerated from liability. The plaintiff may proceed against that defendant later as if no suit or dismissal had happened.

Can a plaintiff dismiss a principal obligor while keeping the sureties in a Texas suit?

Generally, no. Rule 161 bars dismissing a principal obligor without also dismissing the parties who are only secondarily liable, unless a statute allows it.
