Hi Steps,
There are three parts to a contract; Unless all three are present, there is no contract..
These are;
1, An offer; I will do whatever, give you whatever.
2, An acceptance; Oooh, yes ok!
Now, both parties have to be clear about what is on offer, or there is no contract.
If i want to buy ten tons of wood, and it turns out that it is ten tons of sawdust, then there is no contract, because that was not what i intended to buy, when i entered into the contract.
In the same way, if you contract to replace a plug socket, but then you rewire the house, do not expect to get paid, as this is not the "offer" that the householder "accepted"
Finally, a "consideration"
Basically, this means that you have to be getting paid. For example; If i sell you an item, and it turns out to be faulty, you can sue me, because the goods did not "conform to contract" They did not perform as intended.
If however, i GAVE the item to you, then there is no contract, and so you can do nothing [as common sense would suggest]
If i gave you a car with faulty brakes, you could definitely not sue me for that in the same way as you could if you had bought the car from me, but i presume you could sue me for negligence instead, as giving someone a car that you are aware that they are going to use, knowing that the brakes were faulty, would obviously be negligent, you could reasonably forsee that there might be an accident.
One thing to be very careful of though; Many years ago, case law established [and i do not know if this is still the case] that if a "professional" person gave you his advice on a subject, then he had to stand by that advice, and indeed, could be sued if he made a mistake, EVEN IF HE GAVE HIS ADVICE FOR FREE....
