Spousal Privilege

Spousal privilege is a class protection of certain communications between husband and wife. It is a protection that is separate and apart from spousal competency.[1]

A spouse who is found to be competent and compellable may still invoke privilege to protect their communications.[2] The privilege belongs to the recipient spouse.

This class of privilege does not exist at common law, but rather was created by way of s. 4(3) of the Evidence Act, which states:

4...
[omitted (1) and (2)]
(3) No husband is compellable to disclose any communication made to him by his wife during their marriage, and no wife is compellable to disclose any communication made to her by her husband during their marriage.

[omitted (4), (5) and (6)]

R.S., 1985, c. C-5, s. 4; R.S., 1985, c. 19 (3rd Supp.), s. 17; 2002, c. 1, s. 166; 2014, c. 25, s. 34, c. 31, s. 27; 2015, c. 13, s. 52.

Third parties may "testify to communications between husband and wife that were overheard, intercepted, or otherwise discovered".[3]
