Not seeking legal advice

Mishandled divorces can cause undue stress and financial turmoil. Even if you and your ex are on good terms, issues like home ownership and custody arrangements can get complicated fast. Without a lawyer to guide you, you run the risk of losing your assets or having uncertain child care arrangements.

What to do instead: Find a reputable divorce lawyer or, if the split is amicable, a mediator. Many offer free consultations that may be worth your time.

Taking to social media

Watch what you share on social media: It could be used as evidence during divorce proceedings. Even seemingly innocuous posts could be twisted to make you seem dishonest or irresponsible. For example, if you're seeking (or trying to avoid) alimony payments, that photo of your new Birkin bag should probably wait.

What to do instead: Don't vent about your divorce online, and don't post anything that could hurt your image during the divorce.

Neglecting your individual finances

Ending a marriage affects more than your day-to-day living. Surprising ways divorce can impact your finances include the loss of health coverage, increased child care costs, and even changes to your retirement plan. The financial aftermath of divorce can wreak havoc on your bank account if you're not careful.

What to do instead: Learn as much as you can about your new financial situation, and prepare for potential lifestyle changes by keeping to a budget as you go through the process.

Resolve $10,000 or more of your debt

National Debt Relief could help you resolve your credit card debt with an affordable plan that works for you. Just tell them your situation, then find out your debt relief options.⁴ Please note that all calls with the company may be recorded or monitored for quality assurance and training purposes. Clients who are able to stay with the program and get all their debt settled realize approximate savings of 45% before fees, or 20% including our fees, over 24 to 48 months. All claims are based on enrolled debts. Not all debts are eligible for enrollment. Not all clients complete our program for various reasons, including their ability to save sufficient funds. Estimates based on prior results, which will vary based on specific circumstances. We do not guarantee that your debts will be lowered by a specific amount or percentage or that you will be debt-free within a specific period of time. We do not assume consumer debt, make monthly payments to creditors or provide tax, bankruptcy, accounting or legal advice or credit repair services. Not available in all states. Please contact a tax professional to discuss tax consequences of settlement. Please consult with a bankruptcy attorney for more information on bankruptcy. Depending on your state, we may be available to recommend a local tax professional and/or bankruptcy attorney. Read and understand all program materials prior to enrollment, including potential adverse impact on credit rating. "Debt-Free" applies only to enrolled credit cards, personal loans, and medical bills. Not mortgages, car loans, or other debts. Results vary.

Not dividing marital debts

Dealing with debt and divorce simultaneously can feel overwhelming, but your debt obligations don't go away when you split. You'll still be on the hook for joint balances, and these can hurt your personal credit if you don't come up with a debt division plan during the divorce.

What to do instead: Work with ex and your respective attorneys or shared mediator to divide joint debts. Then, make sure the plan is in writing.

Focusing on short-term wins instead of long-term costs

Splitting assets without considering their future value could mean leaving money on the table. It might also mean opening yourself up to tax consequences down the road. This is especially detrimental if you're trying to build your wealth after the divorce.

What to do instead: Before you divide your assets, estimate what they might be worth later on and what they might cost you.

Hiding assets

The thought of losing money in a divorce is a startling one, but trying to conceal your assets isn't a good idea. In fact, hiding assets is illegal and opens you up to possible perjury charges. Anyone who helps you, like family members or bosses, is also at risk for criminal charges if they lie under oath.

What to do instead: Be honest and transparent about your finances. It's that simple.

Assuming the divorce settlement will go your way

The outcome of your divorce isn't guaranteed until everything is finalized. There are several factors that contribute to the final outcome, including the figures for spousal and child support. Failing to consider worst-case scenarios could lead to unwelcome surprises.

What to do instead: Start making wise money moves now to keep you from living paycheck to paycheck later.

Not keeping detailed records

Maintaining accurate records isn't just your lawyer's responsibility. That falls on your shoulders, too. If you don't hold onto important documentation and take notes as the divorce develops, you might have a harder time recalling key information when you need it most.

What to do instead: Keep a notebook with important dates and information. Write down the events leading up to the divorce, details about interactions with your spouse and your attorney, and any concerns you have as you go through proceedings.

Acting on emotion

Even though divorces are inherently emotional, making decisions in the heat of the moment can have unintended consequences. Acting out of spite can negatively affect your relationship with your ex, as well as your kids. It could also spell trouble if your divorce goes before a judge.

What to do instead: Try not to make decisions while emotions run high. Talk to a therapist or counselor if managing your mental health becomes too difficult during the divorce.
