Lord Mansfield's Rule: Key Insights into Marital Testimony and Evidence

Definition & Meaning

Lord Mansfield's rule is a legal principle that prevents both partners in a marriage from testifying about whether they had access to each other during the time of conception. This rule aims to uphold the presumption of legitimacy for children born during the marriage, meaning that a husband cannot deny paternity based on claims of non-access to his wife. The rule is named after Lord Mansfield, who established this principle in the 18th century.

Real-world examples

Here are a couple of examples of abatement:

In a divorce case, a husband may deny paternity of a child born during the marriage. However, under Lord Mansfield's rule, he cannot testify that he did not have access to his wife at the time of conception, as this could undermine the child's legitimacy.

(Hypothetical example) A couple is going through a divorce, and the wife claims that the husband is not the father of their child. The husband wishes to present evidence of non-access, but the court denies this based on Lord Mansfield's rule.
