What we did was to make all pay into the joint account, and pay out a "stipend" to our individual accounts. But, this demanded a decision up front that under law the assets were dividing 50/50 no matter who sourced them.

Other people come to other arrangements, this one worked for us. In the early years, I had lower income. Post child, I had sole income, then massively more income, then heading to retirement sole income. It makes no difference, the money goes into the joint account and we pay ourselves a (mutually agreed) stipend.

Managing money as a couple can be challenging, but with the right approach, it can also be a great opportunity to build a strong financial foundation together.
