Provide checklists. As users complete your form, you may well be asking them to provide supporting information or attach supplementary documents where required. Providing a checklist, often at the beginning or end of a form, helps remind users about all the things they should remember to attach, and any further steps they need to go through.
In paper forms the specific sub-questions cannot be hidden from the user when they are not relevant to them - but in interactive forms this is relatively easy to do. Use progressive revealing as much as possible in your form design to shield your users from questions they do not need to see.
Also make sure that you make good use of features like running headers and footers on every page to remind people what the form is, where they are, and what page number they are on.
It is similarly annoying to them when it is a long free text box, making the customer question whether they are answering correctly and sufficiently. Providing response boxes that reflect the anticipated answer length and format reassures people that they are filling them in correctly.
Make the form sections visually distinct by setting the section name in bigger and bolder type, and consider including a contents list on the first page or screen to help people navigate their way through the form.
Customise response boxes to reflect required answers and reduce completion errors. If asking for a persons date of birth, it makes sense to provide a box with the exact number of required digits and an example or guidance note to explain the format that the date should be entered in (DD/MM/YYYY).
