In Lotus Notes, all documents are based on forms that provide the structure for displaying the documents' data.

You use many default forms in Notes, such as the Memo form for mail messages that you compose. You might also use custom forms created by Notes application designers. You can include form names in conditions when you filter incoming mail using mail rules.

1. Select the document in a view.
2. Click File > Properties.
3. In the Properties dialog, "Document" should display as the type of properties. If it is not, click the arrow and select it.
   
4. Click the Fields tab.
   
5. In the left panel, select Form. The form's name is displayed (in quotation marks) at the bottom of the right panel.

You can also check properties for a document while the document is in edit mode.
