Is there a cutoff for that 12 month period to be considered common law? because we moved in together last April which would make it 12 months under the fiscal year

[TurboTaxMary-Ann1 · Accepted solution]

In order to be considered common law, you need to have been living together in a conjugal relationship for 12 months as of December 31, 2017, to claim common law on your income tax return.  However, if you have a child together, you are considered common law even if you have not been living together for 12 months.
