Does a will need to be written by a lawyer, or is it enough to write it myself with witnesses?

A will you write yourself can be valid, but a will prepared with professional help is easier to carry out. In terms of Islamic law, what matters is that your wishes are clear, do not exceed the one-third limit, and are not given to an heir without the other heirs' consent. In practice, home-made wills often have problems: the meaning is vague, the witnesses are also beneficiaries, or no one knows the will exists. If you write it yourself, state the date, sign it, and ask two witnesses who are not beneficiaries to sign it. If your property involves several houses or a polygynous family, it is best to use a syarie lawyer or an accredited trust company. See preparing for death.
