When someone calls my office about a potential disability case, I'm looking for specific things that tell me whether the case has a real shot. After 9+ years of handling these claims, three factors stand out more than anything else.
Below, I break down what makes a Social Security Disability case strong, and what you can do if your situation lines up with any of these factors.
Being Over 50 Changes Everything
If you are over 50, and you have never had a sedentary (sit-down) job in the past, your odds of winning go up dramatically. The SSA has a set of rules called the Medical-Vocational Guidelines, commonly known as the "grid rules," that treat applicants over 50 far more favorably than younger applicants.
Here is why. Under 20 CFR § 404.1563, the SSA classifies people aged 50 to 54 as "closely approaching advanced age" and people 55 and older as "advanced age." These categories matter because the SSA recognizes that learning new job skills and switching careers gets harder as you get older. If you are 50 or older, limited to sedentary work, and do not have transferable job skills, the grid rules can direct a finding of "disabled" without the SSA needing to prove you can do other work.
Beyond the rules themselves, I find that judges also give more credibility to claimants in their 50s and 60s than to someone in their 20s, 30s, or even 40s. The combination of favorable rules and practical credibility is powerful.

Consistent Medical Treatment Is the Foundation
The second thing I look for is whether someone is getting regular medical treatment. Social Security Disability cases are decided primarily on the contents of your medical file. If you are not seeing doctors consistently, there is nothing for a disability judge to base a favorable decision on.
This does not mean you need to go to the doctor every single week. It means you have a treatment relationship with one or more providers, you are following up, and your records document how your conditions limit your ability to function. The more thorough your medical records are, the easier it is for me to build a case.
If you are already getting treatment, make sure the SSA has your latest records. Here is a guide on how often you should update the SSA on your medical information.
A Medical Source Statement from your treating physician can be one of the single most important documents in your file. It connects your diagnosis to specific functional limitations the SSA actually cares about.

A Strong Work History Adds Credibility
The third factor I evaluate is work history. The central question in every disability case is: Can this person go back and work a job on a full-time, gainful basis?
When a claimant can say, "I worked this job for the last 20 years, then I got a new diagnosis, had a surgery, or suffered an injury, and I was no longer able to do my job," that story makes sense to a judge. There is a clear before-and-after.
Compare that to a claimant who does not have much of a work history and says they are applying because their condition recently got worse. That is not necessarily a losing case, but it does not carry the same weight. Judges take a well-documented work-to-disability transition much more seriously.
If you have a long work history, make sure you fill out your SSA-3369 Work History Report carefully. That form is where you show the SSA exactly what your past jobs required, physically and mentally.
Putting It All Together
You do not need all three factors to win a disability case. Plenty of people under 50 get approved, and people without long work histories win too. But the more of these factors you have working in your favor, the stronger your case will be.
