It is said that finances are the number one cause of fights in marriages, some of such fights leading to divorce sef.
Personally I feel these things should be common sense, but unfortunately, people tend to focus on the wrong things i.e "love feelings" when starting out a family that they fail to put the necessary structures in place.
Here are my suggestions to couples who want to have a stress-free life regarding finances-after-marriage...

#0) You better have married a spouse that was working when you met/married them.
Brothers an sisters, You are not here to alleviate the poverty of an idle person, but to run a family and BUILD a lineage with someone.
You cannot be building while the other one is tearing down without replenishing. This is the 21st century. Girls, stop marrying idle bums. Guys, Stop marrying idle thots (I say this with total respect due to real women out here making it happen for themselves and their future families).

#1) Set up a family checking account
Set up a bank account for family affairs where a certain percentage (e.g anywhere from 60%) of everyone's income goes into.
From this account family expenses, house expenses, school fees and family savings will be handled.

Men: If you want to be "a man" about it, maybe 70% - 80% of your income can go in there while only 40 - 50% of her own goes in as women tend to do more of certain things around the home anyway....but BOTH must feel the burn of financially supporting the house. Otherwise, abuse is tantamount (why be fiscal when money is his problem?).

Not having these numbers DEFINED from the get-go is also tantamount to abuse. Any intended change to your percentage contribution number different from the starting numbers should be totally at the discretion/sole-acceptance of the other party. If you want to change your contribution, your spouse agrees whether you can change or they refuse. Totally their choice. Note that this is regarding the PERCENTAGE of income, not the number itself. This will save you from several arguments in the future.

Feel free to adjust as you see fit, but these rigid structures set as you enter the marriage are great starting points for order in said marriage.

#2) Set up a family savings account
Anything above 2-3 months of the usual CORE family expenses from the family checking account go in here.
No one can do anything with this money unless both couple sign off on it. Instruct the bank about this constraint.
(of-course, dead-human switches should apply with such constraints)

#3) Each should have their own private checking account
This is where the other un-contributed money goes to for each party.
Here, do whatever you want with your money. It should be no-one's business.

E.g Use this to buy gifts for your spouse and take him or her out on dates....yes I said HIM or HER. Either spouse can take the other out on dates, not just the man.

This is also from where one spouse can choose to give monetary gifts to the other spouse.

Ladies: ...No. "Borrowing" your husband who is currently without income money to pay the rent is NOT a monetary gift. Put that thing in the family shared account. It is you supporting your family. No be only him waka come.

#4) Love each other
This comes last because emotions (love) must come AFTER logical structure and boundaries otherwise you cannot build.
Building *purely* on emotions is like building on quicksand.

Ok

This will give you financial peace in marriage.

Very useful points
