Customer not paying - can I do this?

[john_p]

I did some contract work for a company. Original contract stated (essentially) intellectual property remained property of myself, until paid in full.

The company have paid 70% of the first invoice, and nothing of two further invoices I submitted for additional works they requested. Chasing payment has of course got me nowhere

Am I within my rights to remove access to the software I have created? Or even just 30% of it?

[john_p]

Should £xxx be all outstanding invoices, or just the initial one though?

They've had multiple chances to give me a snagging list but each time come back with more things. They've been quiet for ages, so I assume they're happy with it.. ho hum

[john_p]

They've said certain issues still need resolving, but haven't detailed these at all. We already had one list of "issues" which were resolved promptly. As far as I'm concerned it meets the spec. One particular "enthusiastic" director suggested they would sue me for loss of business if I didn't fix the system (or suspended it, as I am able to)

Plus they owe a few months of support fees (dated from when the project was initially delivered).

All a bit of a mess, and I don't care about annoying them now - I've started work elsewhere anyway..

[john_p]

Yes this is the plan for tomorrow. I'll definitely press for payment of support fees, and then consider looking at the snagging list. If not, I'll just switch it off
