In an eleventh-hour move, the three organisations have managed to provide £1,200, which is enough for the CAB to start its guidance tutor programme.
The money will tide the bureau over until the result of a lottery bid is known at the end of the summer.
Manager Diana Wilson said that if the charities and the parish council had not stepped in, cuts in the services offered by the bureau had been likely.
In early March, the bureau applied for a grant from East Hampshire District Council's north east area community committee, which would have gone towards providing a guidance tutor for the bureau.
But councillors refused the grant, forcing the CAB's management team to consider cutting services to fund the tutor.
Mrs Wilson said the community had rallied round after an article in The Herald.
"We were very fortunate that two local charities and Lindford Parish Council came to our aid."
The charities, which wish to remain anonymous, donated a total of £1,000, and Lindford Parish Council gave a one-off grant of £200.
"It's absolutely brilliant. The figure is the amount that we settled on when we asked the area community committee for a grant," said Mrs Wilson.
Training at the bureau has now started, with two new advisers being shown the ropes.
"They have just started their competency training, so they will be of use to us in about six months, when they have gone through all the training. It's quite a heavy programme.
"And it's enabled us to go on training, not only the new advisers, but also the existing advisers, because legislation is changing daily and we are constantly having to update the existing advisers on the new rules and regulations."
A guidance tutor is essential to help the bureau to obtain the community legal services kite mark, which will enable it to retain membership of the National Association of CABs.
Mrs Wilson said staff are now keeping their fingers crossed for the result of the National Lottery bid.
"We are all hoping the bid will be successful and that it will give funding for three years. If it is not successful, we will have to go back and talk to East Hampshire District Council."
Bordon and Whitehill district councillor Zoya Faddy said she was pleased services would not be cut, but was angry the organisation had to rely on charity.
"I don't think that the CAB should have to get the begging bowl out and rely on charity. The CAB is a fundamental service which provides extremely good value for money."
p Bordon's CAB is open on Mondays, Tuesdays, Wednesdays and Fridays, from 10 am to 2 pm.
