Hi @Arman,
Thank you for reaching out to Microsoft Q&A forum!
Document Intelligence can recognize signatures in a document using the Custom model API of Form Recognizer. To detect signatures in contract documents using Document Intelligence, you can specify certain fields as signatures. After your training set is labeled, you can train your custom model and use it to analyze documents. The signature fields specify whether a signature was detected or not.
To detect the signatures from documents you need to train by using the Custom template model. Please recheck the model you are using Custom template only.
I hope this helps. And, if you have any further query do let us know.
