Am buying land over the internet
Am not Canadian

My Canadian realtor says its ok, no need to sign a contract with the lawyer

Am scared

If you are scared, you should not do what you are thinking to do. For one, it sounds pretty scary to me to buy land over the internet. Have you actually been to the land? If not, don’t buy. Have you seen a land titles search and looked at notations and charges on title? How about local zoning? Utilities (well / municipal water, etc.)? Are you going to be on the hook for local improvement levies, either now or in the near future? Seen any appraisals or the like to give you some idea of the price asked as compared with the value of the property? Etc. etc. etc.

The way real estate deals happen (at least in BC) is that you get a lawyer (or a notary) to do the Land Titles documents so everything gets registered properly, but usually the realtors do the contract of purchase and sale. Usually this works out OK, but sometimes the realtors make a real mess out of the contracts and it all ends up in court. One main problem in that regard is scrawly hand written things that are scratched out, changed, and scratched out again, leaving everyone to wonder what people agreed to do. My opinion is that you should seek some legal advice from a local lawyer and, after speaking with the lawyer, decide who to hire or whether to hire anyone at all. Don’t buy a pig in a poke!
