Assuming you're in the US, a simple option to avoid the hassle of probate, wills, trusts and that entire industrial complex is to title your accounts or assets as 'Payable on Death' or 'Transfer on Death'. In most states you can amend your bank account, taxable investment account, title to your vehicle, etc to list a beneficiary in the event you die. For retirement accounts like 401(k)s or IRAs you just update your beneficiary within the account and there is no POD/TOD designation.
Each institution has different procedures so look them up on their website or call them. For cars you will probably have to get a new title from the DMV listing the TOD designation on the title under your name. Regardless of the situation it should be pretty simple to do.
The advantage of this approach is that your beneficiary does not need to go through the courts, possibly retaining counsel for probate, and going through the huge hassle it requires. They can contact each institution directly, provide a death certificate and retrieve your assets.
All that said, it's still a good idea to have an estate plan in place to cover contingencies and especially your directives surrounding end of life medical care, power of attorney, etc. If you don't have those in place and a situation arises, it becomes a lot more difficult and decisions might be made against your wishes if you don't have them documented. A reputable lawyer should be able to provide you with something basic that satisfies your state's requirements for a few hundred bucks.
