Separating financial accounts can be a complicated subject for couples, particularly when it pertains to investment accounts. When should you combine accounts, and when should you separate them? You may be thinking it depends on your situation and personal finances. But that’s not exactly right.

It really depends on the type of account you have, more than anything else.

Here are the most common account types and suggestions on how to handle them as a couple.

Checking Accounts

Checking accounts aren’t investment accounts in any sense of the term, but since they are generally the most active of all financial accounts, they’re well worth discussing. The whole idea as to whether or not to have joint or separate checking accounts is wide open to debate.

Here are the advantages of each type of arrangement.

Joint checking works best when:

  • Both spouses are about equally responsible for the financial management
  • When it is agreed one spouse will be primarily responsible for the household budget and paying bills
  • When one partner has a stronger orientation toward financial management and the other doesn’t
  • When one spouse earns all or most of the household income (less justification for separate accounts) — ironically in this case it’s often the non-earning spouse who primarily manages the checking account

Separate checking works best when:

  • There’s concern of two people writing checks and running debit cards out of the same account, and the potential for overdrafts
  • When the couple isn’t necessarily in agreement about budget issues
  • When the income split between the couple is roughly equal, and each have their own set of expenses
  • When one or both partners have a significant amount of job- or business-related expenses

It’s sometimes thought a joint checking account between a couple is a way of cementing the relationship. That may be true on an emotional level, but there may be practical issues that make the joint arrangement unworkable.

Savings Accounts, CDs and Money Markets

Savings, CDs and money market accounts are typically the types of investment vehicles a couple will use to pay for intermediate expenses, such as upcoming vacations, replacing components of the family home (roof, carpeting, etc.), replacing a car, or even for emergency savings. Since they are generally used for a common purpose, it makes perfect sense for these accounts to be held jointly.

It’s also important that accounts of this nature represent shared responsibility. That is to say each partner should feel responsible to make some sort of contribution to the account, in order to help fund the expected need.

It’s also much easier to have such accounts held jointly since the activity level — other than contributions — tends to be minimal. Since these accounts often don’t come with checking or debit cards, there’s little chance of either spouse overdrawing the account.

Investment Accounts

Much like traditional savings vehicles, investment accounts are usually established for some sort of intermediate purpose or at least a goal that’s just short of retirement. Often these accounts are held for the purpose of saving for a child’s college education or for purchasing a vacation home at some point in the future. Those represent common goals, so joint ownership is highly advised.

Once again, the joint nature of such an account increases the responsibility for each partner to fund the account.

It can also be important to share ownership of investment accounts with your spouse for inheritance purposes. If the account is joint, transfer of the account upon the death of one spouse will be automatic. In some states, it can be much more difficult for such a transfer if the account is held in only one name.

Retirement Accounts

There’s not a whole lot to discuss when it comes to retirement accounts, since they are legally established by and for individuals only, and not couples. This applies to all types of retirement accounts, including:

  • IRAs
  • 401(k)s
  • All employer-sponsored plans
  • Some self-employed plans

An account can only be held in an individual’s name; however, you’re typically required to provide beneficiary information, which is usually your spouse. In the event of the death of the owning spouse, the account can automatically transfer over to the other.

Business Accounts

Business accounts can be something of a gray area, and whether they are held individually or jointly depends mostly on the business formation itself.

For example, if the business is established as a corporation, the account should actually be in the name of the corporation itself, rather than in any individual name. However, the spouse who operates the business will have signature authority over the account, though ownership of the account will be retained by the corporation.

Partnerships are another business form where joint ownership of accounts between a married couple isn’t even workable. Since a partnership can involve multiple business partners, ownership and access to any financial accounts will have to be retained within the partnership. The lone exception would be where both spouses are partners in the firm.

Sole proprietorships are the one business form that has potential for joint accounts. This is true because such accounts do not involve ownership by outside parties. Joint accounts between spouses may even be desirable, since many sole proprietorships are in fact joint ventures between married couples. And just as often, one spouse may handle the finances of the business while the other operates the business itself.

Joint ownership of business accounts for sole proprietorships may even be desirable. In the event of the death of the primary sole proprietor, ownership and participation in any of the business accounts by the surviving spouse will enable him or her to have immediate control of the account.

As well, being privy to the activity in the account, and by extension to the workings of the business itself, will be a major advantage to the surviving spouse.

Do you and your spouse have joint accounts or separate ones? How do you manage your personal finances but in a cohesive way?

  1. I think keeping things separate is the way to go. Don’t mix up business with personal relationships. That way if you break up with your significant other, at least your finances don’t take a hit.
