Full Text of Rule 5.440

Text sizeJump to: (a) (b) (c)

Where resources permit, courts should identify cases related to a pending family law case to avoid issuing conflicting orders and make effective use of court resources.
(a) Definition of “related case”
For purposes of this rule, a pending family law case is related to another pending case, or to a case that was dismissed with or without prejudice, or to a case that was disposed of by judgment, if the cases:
(1) Involve the same parties or the parties’ minor children;
(2) Are based on issues governed by the Family Code or by the guardianship provisions of the Probate Code; or
(3) Are likely for other reasons to require substantial duplication of judicial resources if heard by different judges.
(b) Confidential information
Other than forms providing custody and visitation (parenting time) orders to be filed in the family court, where the identification of a related case includes a disclosure of information relating to a juvenile dependency or delinquency matter involving the children of the parties in the pending family law case, the clerk must file that information in the confidential portion of the court file.
(c) Coordination of title IV-D cases
To the extent possible, courts should coordinate title IV-D (government child support) cases with other related family law matters.
End

Plain-English Summary

The same family can generate several proceedings at once, and the risk is two judges making incompatible orders about the same children. Where resources permit, courts should identify related cases to avoid that and to use court resources effectively.

A pending family law case is related to another case — pending, dismissed with or without prejudice, or already disposed of by judgment — if they involve the same parties or the parties’ minor children, if they turn on issues governed by the Family Code or the Probate Code’s guardianship provisions, or if hearing them separately would likely require substantial duplication of judicial resources.

One safeguard travels with the disclosure. Where identifying a related case reveals information about a juvenile dependency or delinquency matter involving the children, the clerk must file that information in the confidential portion of the court file — except for forms providing custody and visitation orders meant for the family court file. Courts should also coordinate government child support cases with related family matters so far as possible.

Frequently Asked Questions

What makes another case "related" to my family law case?

It involves the same parties or their minor children, or turns on issues governed by the Family Code or the Probate Code guardianship provisions, or would likely require substantial duplication of judicial resources if heard by a different judge.

Does a closed case count?

Yes. A pending family law case can be related to a case that was dismissed with or without prejudice, or that was disposed of by judgment.

Will my child’s dependency case become public?

No. Where identifying a related case discloses information about a juvenile dependency or delinquency matter involving the children, the clerk must file that information in the confidential portion of the court file.
