Child tax credit and undisclosed partner

[Taxistaxing]

Trying to determine if you spend around 5 nights a week with a partner (actually engaged if that makes a difference) but between two houses, no joint accounts, is this significant enough to disclose, or would this still not be seen as living together?

I don't think so. 2 houses. No joint accounts. Presumably no sharing of finances. That's still 2 single benefit claimants with their own financial responsibilities

@sittingonacornflake thanks!

I'd say it's if your partner financially contributes to your home in any way, that would muddy the water a lot.
