PROS
Makes managing budget for a household easier
Easy to see what spending and income are
Only one account to monitor
No secrets
CONS
As you’re not married there can be issues with access in the events of incapacity or death of one account holder, if you split there can be issues with the account being misused, bank can choose to freeze it if there’s concerns about access/debt. On mn there’s a great focus on separation/divorce as the end of a relationship but death can and does happen unexpectedly and poor financial organisation can be a nightmare to deal with at such a traumatic time.
No discretion it’s all laid bare so everything from surprise birthday gifts to saving money to leave the other will be obvious
If either party is irresponsible with money or becomes so then their actions affect the others
If either party is remotely controlling with money it can cause issues
Having had a joint account with my ex which he then emptied days after we split without warning leaving me and then toddler dd penniless I would caution anyone against ONLY having that one joint account.
I’ll never have a joint account with anyone again and even if I did I would only have it for joint expenses and pay into it from a separate individual account which I would maintain. The 2 accounts would not even be in the same banking group (if one party of a joint account incurs debt with the bank that they then seek to recover if you have an account within the same banking group in certain circumstances the bank can withdraw funds from an in credit personal account to pay off debt in the joint account)
“We have an account that all the bills come out of and we each pay a set amount in on payday which covers them. It’s not joint though as my DH was bankrupt so we can’t have a joint account. But essentially it is a joint account as we can both access the app, its just in my name only as a technicality.” I believe I’m correct in saying that’s not a “technicality” that’s breaking the law! Certainly the terms of your agreement with the bank!
Your child is only 5 months old, are you on mat leave or a sahm?
You’re extremely vulnerable as a sahm if not married.
It’s also sensible to always have more than one source of funds in case of things like a particular banks card system crashing (which has happened a few times in recent years!)
I now have a current and savings account with one bank but a credit card (that I only use for major purchases for coverage reasons which I pay off immediately but I have it for emergencies too) with a different company and a credit union savings account with a 3rd organisation.
It’s never a good idea to have “all your eggs in one basket”.
Keep your own account that any salary and any money for dc goes into is my advice.
