I am off work on stress leave. Am I able to collect LTD if I also am an owner of a separate company?

You will likely be able to collect LTD in this situation (assuming you pass the medical test), but it does depend on the terms of your specific policy (all policies are different). You should apply right away (as there are deadlines for submitting your application). If your claim is denied for any reason, contact our firm and we will set-up a free consultation for you with an LTD lawyer, to review your options.
