Picture someone who spends an evening filling out a free will template, prints it, and slides it into a drawer feeling like the job is done. It isn't. No one witnessed the signing. A year later, that page would not do what they thought it would.
Quick answer: A good online will covers the decisions that actually matter (guardian, executor, who gets what), builds the document to your state's rules, and tells you exactly how to sign and witness it so it's valid. The common mistakes are skipping the witnesses, using a generic template that ignores your state, and never storing or updating the finished will. The tool that only prints a document, without telling you how to make it real, leaves the most important part undone.
What should a good online will service actually do?
A good online will service does three things: it walks you through the real decisions, it builds the will to your state's requirements, and it tells you how to sign it correctly. The first part is guidance, not just a blank form. The second is what keeps generic templates from failing. The third is the step most people miss, because a will only becomes valid when it's signed and witnessed the way your state requires.
Look for a service that explains each choice in plain language, asks about your state up front, and hands you clear signing instructions at the end. If it stops at "here is your document," you're on your own for the part that counts.
What mistakes actually make an online will fail?
The mistakes that void a will are almost always about execution, not wording. In most states, a will has to be signed by you and witnessed by two adults who don't inherit anything under it. Miss that, and a court can refuse the whole document. Other common errors: using a template written for a different state, naming a witness who is also a beneficiary, and leaving the will unsigned because the tool never explained the signing step.
None of these come from writing a "bad" will. They come from stopping too early. A will that says all the right things but was never properly signed is, in the eyes of most probate courts, not a will at all.
Does it build the will to your state's rules?
Yes, this is the single most important thing to check, because will requirements are set state by state. The number of witnesses, whether a handwritten will counts, and how a will becomes "self-proving" all vary depending on where you live. A one-size template can't account for that. A service that asks your state at the start and generates the document accordingly is doing the work a generic form skips.
HeirLight builds your will to your state's requirements and gives you the exact signing steps for where you live, so the finished will matches the rules that will actually be applied to it.
Can you update it and store it?
You should be able to do both, because a will is not a one-time task. Life changes: a new child, a move to another state, a marriage or divorce. Each is a reason to update. A good service lets you return and revise without starting over, and helps you store the signed original somewhere your executor can find it. A will no one can locate causes almost as much trouble as no will at all.
The bottom line
A will you build online can be every bit as real as one drawn up in an office. What matters is finishing the whole job: the right decisions, built to your state, signed the way your state requires, and stored where it can be found. That last mile is exactly where a good tool should carry you, and where a template tends to leave you.
You don't need every answer today. You just need a clear place to start. Start your will.

The problems are almost never the document. They come from stopping too early: skipping the witnesses, using a template built for the wrong state, or never signing at all. A well-built online will that you sign correctly avoids all three.
A free template can be legally fine if it matches your state and you sign it in front of the right witnesses. What it usually lacks is guidance, so you're left to handle the decisions and the signing alone, which is where free templates quietly fail.
Yes, when the will is built to your state's rules and signed correctly. A court judges an online will by the same standard as any other. Look for a service that shows its sources, explains each step, and tells you exactly how to make the will official.
