A theatre company asked me to write an online writer's

You only pay what you offered to pay unless you choose a premium service.

I would suggest you go back to them and collect you material and advise them you will be having the contract looked over by your solicitor.

It may be best you simply go and ask for it and not warn them you are coming.

In terms of what a fair royalty is, it is not a simple question but you should be talking to the writers guild or your representative body about this type of thing as they would know about what others are paid.

The IP is yours unless you give it to them and if you do then you should be paid a decent fee for it Again this is based on what you think your work is worth.

Also do you know what they will be charging for the course? This is also important so you can work out what you should be receiving.

You will need to have a lawyer that practices in Intellectual property assist you in this matter because they specialise in this area and if they also deal with the writing industry they can also give you ideas on what others are paid.

The law society of QLD can refer you to a solicitor.

Their website is as follows:

But you should go back an take back your work before they copy it and start using it then you will be suing them for copyright breaches and also getting injunctions which will cost you alot of money.

Here is the link to the QLD writers centre and that can also give you some information.

It is a very specialised field and you need a solicitor that practices in Inellectual property.

I think what you have described is not in your favour and giving it to you after you have handed them the work is inappropriate and to your detriment because they now have you work.

I hope this makes sense.
