The first rule of thumb is to inform AIA of any incident that is covered by your policy in writing the soonest possible within 30 days of your encounter. You can reach them through email at MY.LifeClaims@aia.com or head directly to their branches.
Claim form is always a must to initiate a claim. There is different form for different type of incident, fill up only the relevant one:
If none of the above applies, contact AIA customer service care-line at 1300 88 1899 or look for the one you need by logging in to AIA@MyService. Documents or it didn't happen, they'll also need some supporting documents from you as a proof. Check against this checklist to see if you have everything they need.
Once everything's in place, deliver the completed claim form and documents personally to any of AIA branches you find convenient. Rest assured that AIA will process your claim promptly and inform you of the outcome in no time!
