Aretha Franklin left no will. Here’s why you should plan for your death.

Here’s one celebrity trend you should avoid: having no will.

Aretha Franklin, who died Thursday in her Detroit home after a long battle with pancreatic cancer, did not have one in place, according to published reports. She was 76.

Her four sons on Tuesday filed a document with the Oakland County Probate Court in Michigan that lists themselves as interested parties in Franklin’s estate. A niece also asked the court to appoint her as personal representative of the estate.

While you might assume estate planning only applies to wealthy people, that’s not the case. An estate only refers to what you own: financial accounts, real estate and possessions.

Putting a plan in place for those assets helps ensure that upon your death, your wishes are carried out and that family squabbles don’t evolve into destroyed relationships.

In other words, it’s partly about making things easier for your loved ones during an already-difficult time.

Here are some basics that can go a long way toward leaving your affairs in order.

If you have little in the way of assets, you might think you don’t need one. Guess again.

If you pass away without it — called “dying intestate” — the legal system in your state will decide who gets your assets, no matter how massive or meager.

Worse, if minor children are left parentless and there is no will stating who you want to care for them, guess who appoints a guardian? A judge. And that’s after family members have potentially given their 2 cents.

“If no guardian is named, then it can be a free for all,” said Elise Gross, an estate-planning attorney and of counsel to the Presser Law Firm in Boca Raton, Florida. “It could be an ugly and uncomfortable situation, which is not best for the children.”

The person you name as executor of your estate will face what can be a daunting job, so choose wisely.

Things such as liquidating accounts, ensuring your assets go to the proper beneficiaries, paying any debts not discharged (i.e., taxes owed to the IRS), and even selling your home could be among the duties undertaken by the executor.

“You want it to be someone you trust, someone who’s financially savvy enough to understand things and can deal with the beneficiaries,” Gross said. “It’s a big job.”

In other words, just because you’ve known your best friend since elementary school doesn’t mean handling the challenge of being an executor is up her alley. Same goes for a trustee, if you set up a trust.

People often mistakenly think that in their will, they can name who gets the money in retirement accounts, life insurance policies and the like. Wrong.

The person listed as the beneficiary on each of those accounts will get the money even if your will says otherwise.

Also, when life changes, remember to update the beneficiaries on those accounts.

Also known as a living will, this document outlines your wishes if you become incapacitated due to illness or injury.

Say you are on life support. Instead of a loved one making the agonizing decision whether to end all life-saving measures, your wishes would be specified in a legal record.

If you become incapacitated, the people you grant powers of attorney will handle your medical and financial affairs if you cannot.

Often, the person who is given this responsibility when it comes to your health care is different from whom you would name to handle your financial affairs.

As with choosing an executor, make sure whoever you hand the financial reins to is trustworthy and smart.

“This person can be messing with your assets while you’re alive,” Gross said. “You’re giving someone signficant power.”

While it can be hard to imagine your own death, picture your family having to search through drawers for your original will, documents regarding your bank accounts and other assets, and maybe even your Social Security number.

The best way to avoid forcing them to deal with that task on top of mourning is to leave an organized list of information that the will’s executor will need to settle your estate. Be sure this includes passwords so your online accounts can be accessed.

“I think there should be a binder that has all the information and you tell whoever is in charge where they would find it,” Gross said. “Just be careful where you put it, and don’t make any copies.”
