Investment agreements can take many forms and there is no one standard document.
How the investment is being made and what is offered in return should be considered carefully. Both those making the investment and those receiving it, can find that acting in haste can lead to repenting at leisure.
Those receiving the investment can – at a later date – resent what they have “given away” for what with hindsight (and at a time when the investment is not as needed), seems to be little value, whilst the investors expectations can also be left unsatisfied. In seeking an investment, a business will often give promises and assurances as to profitability, but unless these promises are being backed up with protections, many investors can learn the hard way that the value of any investment can go down as well as up.
