§ 436 Competence of spouse

Here's a plain English summary of this rule:

In family court cases about paternity or support (covered under section 433), a husband and wife can testify against each other. Normally, there are limits on spouses testifying against one another in some legal proceedings, but this rule removes those limits for these specific hearings.

This rule also allows a spouse to testify about "non-access," which means they can tell the court if they were not together during the time a child would have been conceived. This kind of testimony can matter in cases where the court is trying to figure out who a child's father is.

So if you are involved in a paternity or support case in family court, know that your spouse can be called to testify, even about private matters like whether you were together during a certain time period.
