Successful marriages rely heavily on the ability to work as a team, not least when it comes to finances. Most couples are now both working, meaning you will need to find a way of fairly splitting the bills. Firstly, you should know the full details of your mortgage cost, council taxes, and household bills before moving into the home. From here you can decide whether to go 50/50 or use weighted payments in line with your individual salaries. Of course, you should consider how much money you each invest into the deposit. Avoiding financial arguments will make married life far happier.
